It would be nice if one could submit feature requests and bug reports from inside DrJava itself.
I understand that having a person to contact (and thus a necessary login to sourceforge) might be useful, but having to login, and to find then copy/paste system info from DrJava into sourceforge could be discouraging many from submitting their feedback, or submitting it anonymously and deficient (wrt included system info) anyways.
I thus see submitting feedback from inside DrJava may have many benefits that counter the only possible drawback I can think of (anonymity). (Is it possible to let users to login to their sourceforge accounts from inside DrJava? If so, that could be awesome, but it seems to me that may not be easy to do, or even possible).
